Cemented Carbide Drill Bits

Cemented carbide, which is also sometimes referred to as "Heavy Metal", has a compressive strength much greater than any hard metal or alloy. Because its highly resistant to abrasion, it is ideal for use in a variety of wear applications. Cemented carbide is very suitable for high quality requirement for making cemented carbide drill bits to be used in mining field.

Cemented carbide drill bits have always been our main products?through the years; we have developed expertise in manufacturing a wide range of them. Cemented carbide drill bits are widely applied to oil drilling presented and snow removal, snow plows or equipment. Cemented carbide drill bits are used in coal drilling tools, cutting tools, mining machinery and road maintenance tools for snow removal and street cleaning. Cemented carbide drill bits of mining are widely applied to stone tools, mining tools for use in quarries, mines, tunnels and civil constructions.

Cemented carbide drill bits can be used?to reduce wear on?rubbing surfaces found in roller cone drill bits, diamond bits, down-hole stabilizers, and numerous other applications.

Cemented Carbide Drill Bits
	Cemented carbide drill bits are suitable for serving as drill heads of heavy rock-digging machines, plumbun heads which are used in deep hole drilling terrace vehicles. We can provide all kinds of drill bits according to the drawings and samples including non-standard styles. Grades for Cemented Carbide Drill Bits
